Autonomous Navigation of Turtlebot Using ROS

Autonomous Navigation of Turtlebot Using ROS

In the previous lesson, we first understood what navigation, path planning, and control mean in robotics. Then, we launched the navigation package (amcl package) in Gazebo to localize a robot during motion. Afterward, we set an autonomous motion for a robot starting from the initial pose to the target pose using RVIZ. navigation, path planning, and control in ROS using amcl package In this lesson in the series of lessons on ROS tutorials, we will start with navigation without RVIZ, we will write our own code and we will create the auto_nav package (autonomous navigation) for our final project.

Navigation, Path Planning & Control Using amcl Package

In the previous lesson, we understood what localization, mapping, and SLAM mean in Robotics, we also launched the Turtlebot3 gmapping package in Gazebo, and drew a global map using the robot's LIDAR (localization + mapping). turtlebot3 gmapping package In this lesson in the series of lessons on ROS tutorials, we will first understand what navigation, path planning, and control mean in robotics. Then, we will launch the navigation package (amcl package) in Gazebo to localize a robot during motion.

Labrador Retriever Robot: an Assistive Robot for Elderly

Labrador Retriever Robot: an Assistive Robot for Elderly

Labrador Systems, a company that makes assistive home robots, recently made Labrador Retriever which is an autonomous service robot to make life easier for senior adults or people with disabilities to move or "retrieve" things at home. Image credit: Labrador Systems Initially, the robot should be trained to build a map for the home. This training is done using a set of routes and stops (places that the robot should go, such as by the fridge) based on the customer's needs and preferences. Image credit: Labrador Systems Then the robot can navigate through the home autonomously using 3D vision and…
